The inconceivably grand project of utilizing cosmological-scale phenomena and the properties of the universe as a whole for energy, computation, or engineering. This includes tapping the rotation of galaxies for energy, using cosmic inflation as a computational substrate (a "inflationary computer"), harvesting the energy of gradually decaying dark matter, or manipulating the large-scale structure of spacetime to create stable megastructures. It's engineering on a scale where the projects are visible to other galaxies and their completion times are measured in galactic years.
Example: "The Kardashev Type IV civilization didn't build Dyson Spheres; they were into universe harnessing. They'd gently torque the magnetic fields of galactic clusters to generate power, a process so slow and vast it made plate tectonics look twitchy."
